Introduction
3.0INTRODUCTION
Congratulations on your choice of the Liebert UPStation GXT2U™
Uninterruptible Power System (UPS). It provides conditioned power
to microcomputers and other sensitive electronic equipment.
Upon generation, AC power is clean and stable. However, during
transmission and distribution it may be subject to voltage sags,
spikes, or complete power failure that may interrupt computer operations, cause data loss, or even damage equipment. The Liebert UPStation GXT2U protects equipment from these disturbances.
The Liebert UPStation GXT2U comes in nominal power ratings of
700, 1000, 1500, 2000 and 3000 VA. Complete model specifications
appear at the end of this manual (see 12.0 - Specifications).
The Liebert UPStation GXT2U is a compact, “on-line” UPS. An on-line
UPS continuously conditions and regulates its output voltage,
whether mains power is present or not. It supplies connected equipment with clean sinewave power. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the Liebert UPStation GXT2U features a light-emitting diode (LED) display to indicate either load percentage or battery
capacity depending upon the mode of operation. It also provides selfdiagnostic tests, a combination ON/Alarm Silence/Manual Battery
Test button, a Standby button, user configurable program, and two
levels of alarms when the unit is operating on battery.
The Liebert UPStation GXT2U has an interface port for communication between the UPS and a network server or other computer systems. This port provides detailed operating information including
voltages, currents, and alarm status to the host system when used in
conjunction with Liebert MultiLink™ software. Liebert MultiLink
software can also remotely control UPS operation.

4.1Transient Voltage Surge Suppression (TVSS)
and EMI/RFI Filters
L
N
G
These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio frequency interference
(RFI). They minimize any surges or interference present in the mains
line and keep the sensitive equipment protected.
In normal operation, the rectifier/power factor correction (PFC) circuit
converts mains AC power to regulated DC power for use by the
inverter while ensuring that the waveshape of the input current used
by the UPS is near ideal. Extracting this sinewave input current
achieves two objectives:
• The mains power is used as efficiently as possible by the UPS.
• The amount of distortion reflected on the mains is reduced.
This results in cleaner power being available to other devices in the
building not being protected by the Liebert UPStation GXT2U.
4.3Inverter
In normal operation, the inverter utilizes the DC output of the power
factor correction circuit and inverts it into precise, regulated sinewave
AC power. Upon a mains power failure, the inverter receives its
required energy from the battery through the DC to DC converter. In
both modes of operation, the UPS inverter is on-line and continuously
generating clean, precise, regulated AC output power.
5
Page 10
Major Components
4.4Battery Charger
The battery charger utilizes energy from the mains power and precisely regulates it to continuously “float charge” the batteries. The batteries are being charged whenever the Liebert UPStation GXT2U is
plugged in, even when the UPS is not turned on.
4.5DC to DC Converter
The DC to DC converter utilizes energy from the battery system and
raises the DC voltage to the optimum operating voltage for the
inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage, thus increasing reliability.
4.6Battery
The Liebert UPStation GXT2U utilizes valve-regulated, nonspillable,
lead acid batteries. To maintain battery design life, operate the UPS
in an ambient temperature of 20°C to 25°C (68°F to 77°F). Optional
external battery cabinets are available to extend battery run times.
4.7Dynamic Bypass
The Liebert UPStation GXT2U provides an alternate path for mains
power to the connected load in the unlikely event of a UPS malfunction. Should the UPS have an overload, overtemperature, or UPS failure condition, the UPS automatically transfers the connected load to
bypass. Bypass operation is indicated by an audible alarm and illuminated amber Bypass LED (other LEDs may be illuminated to indicate
the diagnosed problem). To manually transfer the connected load from
the inverter to bypass, press the Standby button once.
NOTE
The bypass power path does NOT protect the connected
equipment from disturbances on the mains supply.

8.0COMMUNICATIONS
8.1Communications Interface Port
The Liebert UPStation GXT2U UPS has a standard DB-9 serial port
female connector located on the rear of the UPS unit. Several signals
are provided on this port and are assigned as follows:
* Maximum voltage and current on pins 1, 7, 8, and 9 is 60VDC; 10.0 mA.
(+)
(-)
Open
Collecto
Open
Emitter
8.2Pins 4 & 5 - Remote Shutdown on Battery
This pin is functional only when the UPS is in battery mode. If the UPS
is being powered by the mains, Pin 4 will ignore any signal on this pin.
Pin 4 requires a 5-12 VDC signal to shutdown. This normally comes
form the serial port using Liebert’s contact closure cable. It cannot be
used with just a contact closure unless the relay is used to switch a
voltage source. A 5-12 VDC signal for 1.5 seconds or greater is
required to signal a shutdown. Signals for less than 1.5 seconds will be
ignored. After Pin 4 receives a shutdown signal for 1.5 seconds, the
command cannot be canceled.
A battery shutdown signal on Pin 4 will NOT cause an immediate shutdown. A shutdown signal will start a 2-minute shutdown timer. The
timer cannot be stopped. After 2 minutes, the UPS will shut down.
19
Page 24
Communications
If the mains returns during the 2-minute timer countdown, the shutdown timer will continue until the end of 2 minutes and the UPS will
turn OFF. The UPS must remain OFF for at least 10 seconds even if
AC input power returns before the UPS turns OFF. This serves to
reset and restart the server.
Whether the UPS turns back ON when power is restored depends on
the auto-restart setting: enabled or disabled.
If the auto-restart is disabled, the UPS will not restart after performing the 2-minute shutdown delay.
8.3Pins 5 & 6 - Any-Mode Shutdown
Pin 6 of the 9-pin communication connector is used for “Any-Mode
Shutdown” of the UPS output. This control input may be used in special applications to disable the UPS output power—both Inverter and
Bypass.
The Options tab allows the behavior of the Any-Mode Shutdown feature to be modified. When the program opens, or the REFRESH button is pressed, the UPS setting is read by the configuration program
and displayed.
8.3.1Auto-Enable Output
WARNING
!
Note that when this option is selected and the UPS output is
disabled using Pin 6, the UPS output can turn on
automatically and without warning if the Pin 6 connection is
changed.
8.3.2Pin 6 Logic
WARNING
!
DO NOT CHANGE THIS OPTION from the factory default
setting unless you are ready to install a normally-closed
connection between Pins 5 & 6. This connection must be
maintained to use the UPS or to use the configuration
program again, including the ability to change the UPS
setting back to the default setting using the configuration
program via a serial communication link.
If version 1.6 (or later) is used with an earlier Liebert UPStation
GXT2U model (with an earlier UPS firmware version), the Any-Mode
Shutdown features cannot be changed.
If the configuration program is used with an earlier UPS model (with
an earlier UPS firmware version) that does not support the modification of these settings, the Options tab will display a reminder of the
factory default settings. These cannot be changed.

Maintenance
10.0MAINTENANCE
The Liebert UPStation GXT2U requires very little maintenance. The
batteries are valve-regulated, nonspillable, lead acid and should be
kept charged to obtain their designed life. The UPS continuously
charges the batteries when connected to the mains supply.
When storing the UPS for any length of time, it is recommended to
plug the UPS in for at least 24 hours every four to six months to
ensure full recharge of the batteries.
The Liebert UPStation GXT2U is designed to allow the user to safely
replace the internal batteries. Read the safety cautions before proceeding. Contact your local dealer or Liebert representative to obtain
the appropriate replacement battery kit part number and pricing.
10.1Battery Replacement
CAUTION
!
A battery can present a risk of electrical shock and high short
circuit current. The following precautions should be observed
before replacing the batteries:
• Remove rings, watches, or other metal objects.
• Use a Phillips (crosshead) screwdriver with insulated grips.
• Do not lay tools or other metal objects on top of the batteries.
• If the battery replacement kit is damaged in any way or
shows signs of leakage, contact your local dealer or Liebert
representative immediately.
• Do not dispose of batteries in a fire. The batteries may
explode.
